Debut author Choi sensitively shows two lonely and complicated people who slowly emerge from their shells to risk a close relationship. Unlike her flirtatious mother, Penny Lee doesn’t have much of a social life, but she hopes that things will change when she goes off to college in Austin, Texas. There she meets her roommate Jude's mysterious young uncle Sam, a college dropout who works at a local coffee house. Although they barely know each other, after Penny catches Sam in a vulnerable moment, they agree to be each other’s emergency contacts. Gradually, the two become digitally inseparable, sharing their deepest secrets and dreams without the humiliating weirdness of having to face each other.
